In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this activity, learners will go outside and create a constellation.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this activity about gravity (page eight of the pdf), learners will very simply explore how gravity affects objects using balls and toys.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

Learners conduct a "blind" taste-test of several types of enhanced or fitness water drinking water that has commercially added substances like vitamins, sugars, or herbs.

In this activity, learners use their imaginations and picture a scene in their heads.

In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

This activity (on pages 16-23) lets learners measure each other's vital signs—the signs that help doctors understand what's going on in a patient body.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this hands-on botany activity, learners sprout vegetables in film canisters.

In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.

In this math lesson, learners use the setting of a flower-making fundraiser to explore a variety of patterns. Learners examine the patterns in a flower design made of triangles surrounding a square.

In this math activity, learners use non-standard measurement (paces) to find the distance from one point to another. Learners practice estimating and measuring distances .

In this optics activity, learners discover basic lens-making techniques by using a tennis ball to make a lens out of ice.

In this math lesson, learners compare products to determine the best product.

In this activity, learners explore how casts of fossilized bones are created and used to learn about dinosaurs. Learners make observations, draw diagrams and share their findings.

In this environmental science activity about biodiversity, learners play a game to discover the effects of non-native species on an ecosystem.

In this activity (on page 134 of the PDF), learners explore reaction time.
